geet is dadi's favourite bahu..... she has achieved it even before getting married into d family... i doubt dadi's opinion on geet wont change after getting married or if her truth is out.....n beofre dadi thinks of anything else...... geet herself would let d truth out bout her past 2 dadi...... this would only elevate dadi's opinion on geet's character...not degrade it... but i would want the truth out before NT spoils dadi's mind about geet.... even if she trusts geet a lot.... a small sliver of doubt will be ther bout geet if NT spoils her mind......
